            The OpenCL functions enabled by the <code class="function">cl_khr_d3d10_sharing</code> extension allow applications 
            to use Direct3D 10 resources as OpenCL memory objects. This allows efficient sharing of data 
            between OpenCL and Direct3D 10. The OpenCL API may be used to execute kernels that read and/or 
            write memory objects that are also Direct3D 10 resources. An OpenCL image object may be created 
            from a Direct3D 10 texture resource. An OpenCL buffer object may be created from a Direct3D 10 
            buffer resource. OpenCL memory objects may be created from Direct3D 10 objects if and only if the 
            OpenCL context has been created from a Direct3D 10 device.
